Deep learning is a type of machine learning that uses artificial neural networks to enable digital systems to learn and make decisions based on structured and unlabeled data. In general, machine learning trains artificial intelligence systems to examine and learn from experiences received through data, recognize patterns, make recommendations, and fully adapt.
Digital systems with deep learning do not just respond to rule sets. They learn from examples. Then they use this information and react like humans. They also behave and perform.
What is Deep Learning?
Deep learning, also known as Deep Learning – DL; is expressed as the ability of intelligent machines to comprehend and learn. It is designed inspired by the structure and working principle of the human brain. It is an extremely critical technology that makes autonomous vehicles a reality. Deep learning allows us to get closer to creating machines that think and feel.
Deep learning is a sub-branch of machine learning that works by imitating the functioning system of the human brain in processing data. It enables machines to learn without human supervision. It provides capabilities such as perceiving and translating spoken words, identifying objects, and making decisions.
How Does Deep Learning Work?
The training process in the deep learning system takes place by changing the actions of a system based on a feedback loop. There is a reward for each correct action in the learning system. At the same time, there is a penalty for the wrong ones. The system tries to improve its actions to maximize the reward.
Deep learning is possible with artificial neural networks. All this is inspired by the neural networks of the human brain. Sensors, the artificial equivalent of neurons, come together to form artificial neural networks. The term “deep” is used to indicate the number of hidden layers in neural networks. Traditional neural networks contain two to three hidden layers. Deep networks, on the other hand, have up to 150 layers.
Why is Deep Learning Important?
Data scientists and developers use deep learning software to analyze both large and complex datasets, perform complex and non-linear tasks, and respond to text, audio, or images faster and more accurately than humans in general. All these features, which have many practical uses, are also recognized as a modern innovations. All of the things that enable driverless car models to process images and distinguish pedestrians or smart home devices to understand voice commands are deep learning.
What is Deep Learning Algorithms?
Algorithms to be used during the creation of deep learning architectures are of great importance. These algorithms may differ according to the type, size, structure, volume, and parameters to be used. To give examples of algorithms;
- Convolutional Neural Network (CNN),
- Recurrent Neural Network (RNN),
- Restricted Boltzmann Machines (RBM),
- Deep Belief Nets (DBN).

Deep Learning and Artificial Intelligence
Artificial intelligence encompasses machine learning, where machines can learn through experience and acquire skills without human involvement. Deep learning is defined as a subset of machine learning in which artificially shaped neural networks and algorithms inspired by the human brain learn from data.
What are the Differences Between Deep Learning and Machine Learning?
We can list the differences between deep learning and machine learning as follows:
- Hardware dependencies; Machine learning can be done on low-end machines. Deep learning requires high-end machines.
- Number of data points; In machine learning, a small amount of data is sufficient at the prediction point. Deep learning requires a large amount of data.
- Learning approach; In machine learning, the learning process works in small steps. This is faster in deep learning.
- Feature acquisition process; In machine learning, users learn features. In deep learning, information is taken from data.
- Execution time; It takes a little time in machine learning. In deep learning, this takes longer.
- Output: In machine learning, the output is a numerical value. In deep learning, the output can be in the form of sound or score.
